IMPROVEMENT iN ADJUSTABLE ATTACHMENTOF PUMP-BARRELS TOTHEIR BASES.

The Schedule referred to in theseLetters Patent and making part of the same.

To all whom it may .conce-r11.'

A and B, holding thecyliuder to its base, by means of the screw-bolts R and S and ange K.

Figure 2 represent-s a vert-ical view of the base of the pump.

. -Figure 3 represents a View of the under side of one of the detachable ears.

The nature of my invention consists in providing the lower part of the working cylinder of apump, with a flange, .which projects around and about the cylinder, immediately above the valve-plate or base ofthe pump; and iu fastening the cylinder to the pump-base or valveplate, by means of detachable ears or clamps, two or more, which rest upon this flange, and are fastened to the pumpfbase by means of screw-bolts.

The usual mode of attaching a pump-cylinderto its base is, by casting, with the cylinder, two or more ears or lugs upou the cylinders lower end, projecting ou its sides, and securing together the .base and cylinder, by means of bolts running' through these ears and into the pump-base; These ears are liable to break, and do break easily, and thereby render it a necessity to provide a new cylinder. To remedy this expense and inconvenience, I have devised a plan of constructing the cylinder and ears in separate and in- V dependent part-s, so that upon the breaking of one of these ears, it can be easily and readily replaced, at small expense.

In ordinary pumps, there often is diiculty in setting the pump-spout in the most desirable direction, because `the spout isimmovable or fixed in one direction, and cannot be easilychanged to new positions, for the handle and the spout are immovable.

In the construction of my pump, the spout (not shown in th'e drawings) may be moved to any point iu the circle, by merely loosening the clamps or ears and the screw-bolts, and rotating the pump-cylinder` On its own axis, so that the spout may point iu any desired direction.

In fig. l is shown the flange K, around and about the lower portion of the cylinder, the detachable ears A and Bin position, resting upon the flange K, and the bearings D provided 'for them ou the pump-base, secured to the pump-base bythe screw-bolts R and S.

Fig.4 2 shows a vertical view of-the pump-base, provided with the hearings `DD for the ears A and B, the socket RS for the screw-bolts R S, andthe bearing C for the support of the valve and pump-cylinder.

Fig. 3 shows a vertical view of the under side of One Of the detached ears, with the curved edges, adapted to the curved surface of the cylinder and the curved edge of the flange K, the bolt-hole S', the bearing D', and the bearings O P, adapted to rest upon the flange K. These ears are made in such manner as to gain the force and advantage of a tripod, having the two surfaces O I to rest upon vthe flange K, and the projection a' upon the clamp, dottedlines ig. 3, or the projection a l1, dotted lines 1ig 2, upon the 'pump-base, as the third foot of the tripod, Vor third point of contact; or the ears may be made witlra flat under surface, D', to rest upon a dat bearing, D.

By this form of clamps, there is a readier adaptation ofthem tothe position of the pump-cylinder, and consequent greater firmness and steadiness given tO the pump.

Figure l shows the cylinder in position, resting upon the valve-plate, and secured inA its place by the detachable ears A Band screw-boits It S, in the inanu'er hereinbeiine described.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the detachable ears or clamps with the cylinder, arranged to turn on `its Ow'u axis, inv

order to set the spout in any desired direction.
